The Baader RCCI (Rowe Coma Corrector) is a novel Coma Corrector by Dave Rowe with a triplet lens design optimised for f/4 Newtonian telescopes but will deliver impressive results when used with focal ratios f/3.5 to f/6.
The RCCI has a longer than usual chip distance of 91.5mm from the T2 thread. The long focus distance is perfect for larger setups such as a filter-wheel with Off-Axis-Guider or Adaptive Optics.
Perfect for the Atik EFW2 and OAG.
If you want to connect a camera without an Off-Axis Guider via a T-Ring we recommend a Baader VariLock 46 T-2 extender (2956946 #25V) with an engraved half millimetre scale - the ideal distance can be set quickly and easily.
To sink the RCC further into the focuser the knurled ring can be unscrewed.
